BUNCH BULDER.

Application filed Ill/[ay 9, 1925.

'lhis invention relates to bunch building,` mechanisms for the buiider motions oi? spinning; trames, and particularly to a bunch builder motion which acts upon the builder l arm to prevent the cam normally operating' on the builder arm 'from shitting' the builder arm to its Alull extent, or in other word: a bunch builder mechanism which inm'iediately a'lter drilling` pern'iits only the apices ot the cam points to operate upon the builder arm so that only a short oscillatory motionis Aiven to the builder arm and which, after the bunch is completed, auton'iatically permits the cam to operate upon the builder arm to secure the full reciproeation ot the builder arm and thus the full reciproca-tion ot the ring' rail under the builder motion.

A 'further object is to provide a mechanism ot this character which is relatively simple, compact, and which is so constructed that it is a relatively easy matter to provide for any desired number ot winds olf the filling' upon the bobbin in order to 'torni the bunch so that only a 'few winds ot the 'Killing may be placed upon the bobbin as desired or as many as desired.

A still 'Further object is to provide a motion oi this character which will provide a bunch wherein the yarn is not disposed upon the bobbin by any up and down movement ot the ring; rail at all but is wound upon the bohbin without any traverse.

Another object is to provide a mechanism ol. this character wherein the limitation ot the movement ol' the builder arm is secured by a member operatively mounted upon the builder arm and shifted into action when the iframeis dotted, Vwhich is provided with gear teeth engaging` pinion on the cam shaft, and which will operate a length ot time dcpendentupon the number of gear teeth on the member, this member bein@y approximately sector-shaped and when it escapes lirom the `rear wheel or pinion droppingI down into its inoperative position immediately, thus permitting the resrular traverse ot the ring' rail to be resumeds Other objects will api'iear in the course ot the 'following` description.

lt'iy invention is illustrated in the accompanying` drawings, wherein y Figure l is a fragmentary front elevation oi: a spinning# 'traine having' my improved bunch building' mechanism applied thereto;

Referring` to these drawings, it will be seen that l have illustrated su'lcient of a spinning; mechanism to illustrate the application oii my invention, and referring' to these drawings A. designates part of the frame o't the spinningmechanism, B the spindle raiL i@ the ring rail, and D the spindle or bobbin. The rail C is mounted upon vertically shiftable rods E operated by the usual rockers l?, these rockers being connected to each other in the usual manner and each of these rockers having` the form of a "ll-shaped lever, one arm of which is weighted, as at y, the other arm extending` beneath the toot or the vertically reeiprocatable ring rail carryingrod E.

Connected to the upper end ot the rocker F .is the chain G which extends over the pulley g and which extends down to the builder arm l-l, this builder arm being of an ordinary construction and provided with the usual drum l operated by means of' the wormc' carried upon. the piclr shaft J, which in turn carries the pielr wheel j which is operated by the usual pawl or like member so that as the arm ll moves upward the piek wheel 7' will be engaged by the pawl and given certain predetermined revolution which will cause the nnwinding of the drum l to permit the chain G to slack up and thereby permit the ring` rail to move higher. rlhe arm t'l is operated by means of the main cam K which is illustrated as a fourlohed cam but may be of any suitable form, this cam operatingr upon a roller carried by the arm H. Se far l have described the ordinary and common builder motion found on spinning machines In order to carry out the purposes of my invention, l provide a supporting rod 10, the upper end ot which is 'formed with a longitudinally extending,` slot l1 large enough to receive and slide upon the shaft 7c olI the cam K. Intermediate its ends this supporting rod 10 is formed with a longitudinali-7 extending slot 12 and at its lower end it is 'formed to pivotally connect to a pin 13 which is operatively connected by a bracket 14- or like device to the arin H.

Mounted in the slot 11 is a pin 15.7 one part of which is screw-thrciulcd, as at 1G? to receive upon it the nut 17. rlhe other half oit this pin15 is cylindrical in forni and a cotter pin 18 extends through the extremity ol this end of the pin. Separating the screwtl'ireaded portion 16 trom the main part of the pin 15 is a collar 19. |The screw-threaded portion ot the pin is adapted to be placed through the slot 11 and` `adjusted therein and held by the nut 17, and adapted to be slipped upon thisscrew-threaded portion 16 rbetere it is placed in position is an annular member 2O having' outwardly projecting` clutch teeth. The clutch teeth are arranged and the member is so formed as to partially surround or enclose the collar 19, and adapted to be disposed upon the cylindrical portion ot the pin 15 is a wheel formed with interrupted gear teeth ot a peculiar character, as will be later described, this wheel which is in the natureof a cam being designated 21. The inner tace of this wheel is also pror vided with clutch teeth 22 and is hollow so as to partially surround andv enclose the collar 19, and when this gear 21 is placed upon the pin 15 the teeth 22 will engage with the teeth on the member 20 and the rear wheel will be locked upon the pin 15 for rotation therearound. rllhis wheel 21 is preferably somewhat sector-shaped and is cut away at a plurality of points to 'form approximately ll-shaped valleys 24 between outwardly projectingarms 25. As illustrated, there are live oi' these arms, though l do not wish to be limited to this number, and the extremity of each arm is formed with gear teeth 2G. I have illustrated three gear teeth upon the extremity oteach arm, but here again I do not wish to be limited to this number.

Connected to one of the end arms 25 is a two-part link consisting of the lower section 27 and the upper section 2S. The upper section 28 has an aperture tor the passage ot' the shat't la and swings loosely upon this shaft outward ot the support-ing rod. rlhe lower end ot this section 27 carries an outwardly projecting pin 29 and the section 2T is. therefore, pivotally connected to this section 28 by means ot' this pin 29. The seetion 27 is longitudinally slotted, as at 30, and a pin 31 on one ot' the arms 25 engages in this slot and operatively connects this arm to the sectional rod :termed of the inembers 27 and 28.

llt will be noted that the wheel 25 is in the nature of a cam and that the gear wheel 32 with which the member 25 operates constitutes an abutment against which this cam operates in order to alternately shiiit the arm H downward and permit the arm H to iuovc upward. This cam is operated by the rear wheel engaging with the teeth on the extremity ot the arms 25. The spaces between these arms constitute the reentrant portions ot the cani whilethe protuberant portions oi the cam are formed by the arms 25.

"lhe operation ot this invention so tar as described is as telle ln the normal opeiatieu ot' She inechani n while the regular layer oit tillingl is beir ilaced upon the bobl bin or spindle, the i i l'l is relatively raised rofl 1 and the supp( 't (l is li'lited also, the slot to be secured, as illi in lliggure 3. inasmuch as this l() is raised. it `llows that the rod members 27 and 2S will cause j d .orar 25 to occupy the posi- 'eure il. Under these circumstances it is inoperative and the builder motion is operated by means oli the cam l in the usual manner .'ith a tull stroke lgiven to the ring` rail. over the builder arm. lllhen the bobbins lrve been lilled and the oj'ierator dotl's the bob the builder arin is lowered to its full extent. This shifts the supportiup; rod 10 downward relative to the shattt. and inasmuch as the upper end oli the connecting' rod formed by the nieinbers 27 and s held trom downward movement by eno; eine' the shaft 7.,'. it follows that it will net to rotate the cam wheel 25 into a position as illustrated in Figure 5. where the teeth 2S ot tno tirst arm ol the series will engage teeth on the ,uear wheel Then ,he member 25 will be with the as the shi shitted toward the right in Figure 3 by the enf .sement ot the teeth on the wheel 32 and first aru'i until the l.e'ear teeth 25 on the iirst linger or arm are just about to escape from the teeth on the gear wheel 52. At this time the teeth on the second finger have ene'ae'ed the teeth ol wheel 32.

lt will be noted that the spaces 24; on the i'iieuiber are equal in number to the number of protuberances on the cam K. As a lirst arm ot the member 25 moves trom the position shown in Figure 8 to the position radial to the gear wheel 32 to the position shown 'tor the second arm in Figure li. the parte 25,y 2.7 and 2S will permit a slight upward movement ot the rod l() and ot the ll a siii-tht degree as. tor instance. threeeiohths ot au inch. which will cause a, trave ot the riue rail C to this extent. ils the second houfever. comes from a position to the le.,t el" the rod 10 into a position ot iii) approximate alignment with this rod, it will again depress this arm H a slight amount and then as this second arm moves along under the operation ot' the gear 32, another valley 24; will be brought opposite the rod l() and there will be again a slight upward movement ol the arm ll until eventually all ot the arms on the member 25 have been engaged by and disengaged trom the gear wheel 32 and then the bunch is formed. lVhen this occurs, the weight ot' member 525 will cause it to shilt to its normal and inoperative position, as illustrated in Figure 3, and therea'lter the builder motion will operate in its normal and ordinary manne-r.

`While l have illustrated a member 25 having live lingers or arms, l do not wish to be limited to this as it may have as many spaces detined by said arms as there are cam lobes 'on the cam K and under some circumstances as, 'for instance, where it is not desired that any traverse shall be given to the bunch as the lilling is wound upon the bobbin, l provide a cam member 25, illustrated in Figure 9, which is practically a sector ot a circle and which is provided with gear teeth on its periphery adapted to en-A gage the gear teeth 32. This member is also provided with clutch teeth 23 whereby it may be engaged with the member 20.

With this device, during the operation of portion 252L the arm H is held down away 'from any action by the cam K at all and as a consequence the ring rail does not reci procate at all and the yarn will be wraoped upon the bobbin in one plane or approximately in one plane. Obviously the extent ot the toothed surface et the sector gear 25 and obviously the motion of the buneh builder or the size et the bunch built will also depend upon the angular distance between the end arms where the member 25 is provided with toothed arms, as illustrated. rIhus, ier instance, there are two arms on the member 25, it is obvious that Vtilling ior the bunch will be relatively small and it there are three arms it will be larger, and so on, and that by this means it is possible to very readily regulate the amount et play which will i'orm the bunch and if these arms are long relative to the arms shown in .Figure 6, it is obvious that the valleys 2i will be deeper and, therefore, more trav will be given in forming the bunch, whereas it the spaces are. shallower, less traverse will be given in forming the bunch` I do not wish to be limited to the exact construction or formation ot the members 25 or 25a, as this may be modified in many ways without departing from the spirit of the invention, but it will be seen that l have provided a device which is automatically placed in operation and which acts as long as it in operation te give either no oscillation to the builder arm Il, as .where the sector cam 25 is used, or to give only a slight oscillation to the builder arm, as where the interrupted sector gear cam` 25 is used and, as before remarked, it will be obvious that these members 25 may be formed to have arms oi various lengths, ditterent numbers oilI teeth on the extremities el the arms, and may be readily adjusted to suit any circumstances of operation. The device is very compact and talles up but little room. This bunch builder can be used on any make ot spinning machine and the length oit space it occupies on the cam shaft is less than two inches.

Preferably a cover 33 will be used which will partially enclose the cam wheel or the cam member 252 This cover, as illustrated, is lorn'ied with a web 34 having a yslot 85 designed to accomn'iodate the pin 15, this web 311; having` a peripheral wall at the extremities ol the arms 25 and then having a web 3G parallel to the web 34 but annular in term. This cover is made et' metal and is designed to protect the gear 25 or 25 'from being moved by cleaners or sweepers. The slot 35 is slipped back of the ratchet member 20 and the nut l? is tightened up, thus holding` the cover in place. rlhe cover is very -isy to remove but makes a good protection ttor the cam wheel.
